The THB Company serves New England's most complex and compliance-critical facilities — from operating rooms to clean rooms, research labs to commercial towers.
Healthcare facilities are the most demanding environment for HVAC TAB. Operating rooms, isolation rooms, procedure suites, and sterile processing areas all have specific, code-mandated requirements for air pressure relationships, air change rates, temperature, humidity, and filtration — and the stakes of getting it wrong extend beyond comfort to patient safety.
The THB Company brings deep healthcare TAB experience and a thorough understanding of FGI Guidelines, and Joint Commission standards. We've worked at Boston Children's Hospital, Dana-Farber Cancer Institute, Boston Medical Center, and facilities throughout New England. We deliver the documentation your facility needs for accreditation, certificate of occupancy, and ongoing compliance.
Research laboratories place unique demands on HVAC systems — and on the TAB contractors responsible for verifying them. Fume hood face velocities, supply and exhaust air balance in variable-air-volume systems, pressurization of containment spaces, and cleanroom certification all require specialized expertise and equipment.
THB has completed landmark laboratory TAB projects at MIT, Harvard, the Center for Life Science, and 640 Memorial Drive. We understand the operational requirements of research facilities and work closely with mechanical engineers, commissioning agents, and laboratory planners to deliver systems that perform as designed from day one.
Educational facilities — from K–12 schools to major research universities — depend on well-balanced HVAC systems to support learning environments, maintain indoor air quality, and meet energy code requirements. New construction and renovation projects often face compressed schedules and the scrutiny of multiple stakeholders including school boards, state agencies, and accreditation bodies.
THB has served Harvard University, Waltham High School, Marblehead High School, Pompositticut Elementary, and numerous other educational institutions across New England. We're experienced with the schedule pressures of school construction and the documentation requirements of publicly funded projects.
Commercial office buildings, financial centers, media facilities, and mixed-use developments all require precise HVAC TAB to meet tenant comfort expectations, energy code compliance, and certificate of occupancy requirements. Multi-story buildings with complex zoning, variable-air-volume systems, and multiple mechanical rooms demand experienced TAB contractors.
THB has completed commercial TAB projects including Two Financial Center, One Congress Street, the WGBH broadcast studios, and numerous office and mixed-use developments throughout Greater Boston and New England.
Pharmaceutical manufacturing, biotech research, and clean manufacturing environments demand the most exacting HVAC performance of any facility type. Contamination control, precise pressure cascades, validated air change rates, and HEPA filtration systems must all be documented to FDA, ISO, and GMP standards.
The 128 Corridor is home to one of the world's densest concentrations of life science companies — and THB has served clients throughout this ecosystem. Our clean room certification experience and familiarity with validation protocols makes us the right partner for facilities where HVAC performance is a regulatory requirement, not just a comfort issue.
Specialty Capability
Clean rooms are among the most technically demanding environments for HVAC TAB. A Class 1 clean room allows no more than 1 particle (≥0.5 micron) per cubic foot of air — an almost impossibly tight standard that requires verified laminar airflow, HEPA filtration, and airtight pressure management.
The THB Company has specialized clean room TAB experience, including the BMC CyberKnife suite at Boston Medical Center and pharmaceutical and biotech facilities across the 128 corridor.
Verified ACH rates per ISO and FGI requirements for each room classification
Precise positive/negative pressure relationships between spaces
Filter integrity testing and airflow uniformity across filter banks
Validation-ready reports suitable for FDA and regulatory review
